Fox is a common name for many species of omnivorous mammals belonging to the Canidae family. Foxes are small to medium-sized canids, characterized by possessing a long narrow snout, and a bushy tail. Members of about 37 species are referred to as foxes, of which only 12 species actually belong to the Vulpes genus of "true foxes". By far the most common and widespread species of fox is the red fox, although various species are found on almost every continent. The presence of fox-like carnivores all over the globe, together with their widespread reputation for cunning, has contributed to their appearance in popular culture and folklore in many cultures around the world.

I'm personally not a big fan of lumping the Vulpes foxes with the Lycalopex foxes, as it gives the erroneous impression that they're somehow closely related, when they're not. South American foxes (zorros) are actually more closely related to wolves, coyotes and jackals than they are to true foxes.
